You can’t argue with free. When the free thing is a concert by Korn, Café Tacuba or Blue October, why would you want to? All those bands have recently performed at Socorro Entertainment Center, a 10,000-capacity venue opened in 2012 by the Tigua Indians of the Ysleta del Sur Pueblo, owners of Speaking Rock Casino. Located five miles apart from each other, the two sister venues share a symbiotic relationship; one enables the ridiculously low admission prices (some concerts cost a whopping $10), while the other alleviates traffic and generates goodwill. A $1.2 million sound system, beer servings fit for giants and a never-ending slate of world-class acts tend to make people fond of you. 122 S. Old Pueblo Dr., 915-860-7777; speakingrockentertainment.com.
